Peds Fluid Management Flashcards
T/F Children have small surface area to volume ratio
False
Large surface area to volume ratio
T/F kids have immature homestasis mechanisms
true
What electrolyte abnormalities are common in kids?
Hyper and hyponatremia
Hyper and hypokalemia
Why is pediatric intraop fluid mgmt especially important?
Children overload and dehydrate easily
Considerations if giving large amounts of IV fluids
Need to warm them
Consideration with patient on TPN
Continue perioperatively to prevent hypoglycemia
What age group should you always use volumetric chambers, micro-drips and/or pumps?
Children <10 years old
What two IV fluids can you use with blood products?
NS or plasmalyte
What fluids should you use for maintenance and 3rd space losses?
Non-glucose crystalloids
(LR, NS, plasmalyte)
What electrolyte abnormality can occur with “old” PRBCs?
Hyperkalemia
More common if giving more than one blood volume
Is it appropriate to give platelets if your patient looks a bit oozy but you don’t have any labs?
No
Give for dilutional thrombocytopenia or documented decreased platelet count
What blood product do you give for dilutional coagulopathy or surgical “oozing”?
FFP
What all is considered a colloid?
Albumin
Hetastarch
Blood products
What are some other options besides banked blood for high blood loss procedures that you would prob have to prepare in advance for?
- Autologous donation
- Directed donors
- Cell saver
- Deliberate hypotension
- Normovolemic hemodilution
Is is okay to ride out a low Hct in a healthy, hemodynamically stable patient if they are done losing blood?
Yas
Signs of acute hypernatremia
- Irritability
- Coma
- Seizures
Treatment for hypernatremia
Colloid or NS bolus with slow correction of Na+
Signs of acute hyponatremia
- HA
- Nausea
- Weakness
- Confusion
- Irritability
- Seizures
Signs of advanced hyponatremia
- Respiratory arrest
- Irreversible neurologic injury
Treatment for hyponatremia
Slow correction for asymptomatic cases
Treatment for acute hyponatremia
Rapid correction
~except this causes central pontine myelonolysis?? so SOS~
Causes of acute hyperkalemia
- Renal insufficiency
- Massive tissue trauma
- Acidosis
- Succinylcholine with myopathies, burns, motor neuron disease
- Sepsis
- Massive transfusion
- MH
EKG changes with hyperkalemia
- Peaked T waves
- Prolonged PR
- Wide QRS
- Eventual sinusoidal
Treatment for hyperkalemia
- IV Ca++
- Bicarb for acidosis
- Glucose/insulin
Causes of acute hypokalemia
- Vomiting
- Diarrhea
Signs of hypokalemia
- muscle weakness
- Prolonged QT
- Dampened T waves
- U waves
Treatment for hypokalemia
oral supplements if possible or slow IV correction
What are some reasons for fluid loss intraop?
- Surgical blood loss
- Surgical trauma/capillary leaking protein movement into interstitial space (3rd space)
- Anesthesia–> vasodilation –> relative hypovolemia
- Direct evaporation
If your patient loses 300 ccs of blood how much crystalloid would you give to replace it?
How much colloid would you give?
450-900 crystalloid
300 colloid
Excessive amounts of NS given can cause what electrolyte/ acid base imbalance?
Would this occur with LR also?
Hyperchloremic acidosis
Does not occur with LR
What is a situation where excessive amounts of NS may be given because LR is not an option?
What other fluid could you use in this situation?
With massive transfusion
You can use plasmalyte with blood to avoid hyperchloremic acidosis
